Thanks to a nerdy kid's oral report in school and a neighborhood incident, the boys become concerned over the growing rate of copycat incidents involving "murder porn" (i.e., the shows on Investigative Discovery centered on infidelity, spousal abuse, domestic violence,South Park Season 18 DVD and murdering unfaithful lovers) and use Minecraft to distract them from hurting each other.Besides the main series itself, originally-produced South Park segments have appeared in other works, such as sketches for talk shows and award ceremonies. In 1999, South Park: Bigger, Longer & Uncut, a full-length musical film, debuted in theaters. The eleventh season three-part "Imaginationland" story arc was also released as a combined direct-to-video film in 2008. South Park seasons are regularly released on DVD, and starting with the twelfth season, Blu-ray.
